Multicenter Study Comparative Study
Comparison of outcomes after laparoscopic versus open appendectomy for acute appendicitis at 222 ACS NSQIP hospitals.
The benefit of laparoscopic (LA) versus open (OA) appendectomy, particularly for complicated appendicitis, remains unclear. Our objectives were to assess 30-day outcomes after LA versus OA for acute appendicitis and complicated appendicitis, determine the incidence of specific outcomes after appendectomy, and examine factors influencing the utilization and duration of the operative approach with multi-institutional clinical data. ⋯ Within ACS NSQIP hospitals, LA is associated with lower overall morbidity in selected patients. However, patients with complicated appendicitis may have a greater risk of organ space SSI after LA. Academic affiliation does not seem to influence the operative approach. However, LA is associated with similar durations of stay but slightly greater operative times than OA at academic versus community hospitals.

Multicenter Study Controlled Clinical Trial
Multicenter analysis of diaphragm pacing in tetraplegics with cardiac pacemakers: positive implications for ventilator weaning in intensive care units.
Diaphragm pacing (DP) can replace mechanical ventilation in tetraplegics and in trials has assisted respiration in amyotrophic lateral sclerosis patients. This report describes results of DP in patients with cardiac pacemakers. ⋯ DP can be safely implanted in tetraplegics having cardiac pacemakers. Applications for temporary use of DP to maintain diaphragm type 1 muscle fiber and improve posterior lobe ventilation may benefit complex critical care patients.

Regional surgical quality improvement consortiums are becoming more common. Herein we have reported the effectiveness of a statewide consortium focusing on open vascular operative procedures. ⋯ A statewide quality-of-care consortium with timely feedback of data was associated with decreased morbidity over a relatively short follow-up period in vascular patients. Focusing on best processes in real-world practice, such as appropriate transfusion and length of operation, may further improve vascular surgical outcomes.

Our previous investigation demonstrated that despite routine chemoprophylaxis, thrombelastography, which is a comprehensive test measuring the viscoelastic properties of blood, identified a hypercoagulable state in a cohort of critically ill surgical patients that was associated with thromboemobolic events. Furthermore, because thrombelastography allows for the comprehensive assessment of coagulation status, this work suggested that platelet hyperactivity is a component of the hypercoagulable state. We hypothesized that progressive postinjury thrombocytosis contributes to a hypercoagulable state that is associated with thrombelastography. ⋯ Persistent thrombocytosis in critically injured patients receiving routine chemoprophylaxis is associated with thrombotic complications. Subsequent investigation is warranted to differentiate enzymatic from platelet hypercoagulability to ascertain the role of antiplatelet therapy for prevention of TE.

Dedicated skills courses may help to prepare 4th-year medical students for surgical internships. The purpose of this study was to analyze the factors that influence the preparedness of 4th-year medical students planning a surgical career, and the role that our skills course plays in that preparedness. ⋯ Completion of an accelerated skills course results in comparable levels of student performance postcourse across a variety of preclinical backgrounds and clerkship experiences.
